and carrying it around into engagen'icnt with the bed and releasing it at a point below the table, and has for its object to produce a machine of this character which operates efliciently, reliably and expeditiously.

A further object is to produce a simple, strong, durable and inexpensive machine and one to which a stencil sheet may be easily and quickly applied or from which it may be readily removed without injury so that the same stencil can be preserved for future service, as distinguished from the ordinary type of duplicating machine from which a stencil cannot readily be removed without irreparable damage.

A further object isto produce a machine which can be quickly adapted for use with either a stencil, type bed or other printing face.

lVit-h these general objects in view and others as hereinafter appear, the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood refor- ,ence is to be had to the accompanying draw- Fig.

Figure 1, is a side elevation of the machine as-adapted for use with a stencil. Fig. 2, is a front view of the same. Fig. 3, is a top plan view of a portion of the same. Fig. l, is a vertical section taken on the line IVIV of Fig. 2. Fig. 5, is a vertical section taken between the end of the cylinder and the side of the frame shown in Fig. 1. Fig. (3, is an enlarged detail of a part of the cylinder and theadjacent side of the frame, broken away to expose the operative relation between certain parts carried by said cylinder and frame. 7, is a vertical section on line VII of Fig. 1, with certain parts in the plane of said section, shown inelevation. Fig. 8, is

means, theadjacent end of the cylinder and the corresponding end of the shaft, the said section being taken on the line XIXI of Fig. 9. Fig. 12, is an enlarged section on the dotted line XII-XII of Fig. 2, to show only the connection of the gripper shaft spring with the gripper shaft and the cylinder. Fig. 13, is a. detail perspective view of the reciprocatory frame for adjustably supporting the stencil-carrying frame or the type carrying frame. Fig. 14, is a sectional perspective view of a part of the stencil-carrying frame. 15, is a perspective view of a portion of the type-carrying frame. Fig.

1G, is a vertical section taken on the line XVI of Fig.4, but with .the type-carrying frame underlying the cylinder and the latter equipped with an inking roller for the type.

Referring now to the drawings, in which like parts are identified by the same reference characters, 1 indicates the sides of the machine frame and 2 are tie-rods connecting said sides. 3 is a feed-table also connecting and secured to the sides and pitched downwardly and forwardly at a suitable angle and terminating slightly rearward of the vertical plane of the shaft 4 journaled in the sides at a point below the plane of the table.

.3 indicates a slotted cylinder mounted on shaft 'i', the slot extending for almost the entire length and slightly more than half *ay around the cylinder, the non-slotted portion of the latter being provided with a tympan or pad (3. Secured rigidly to one end of the eylii'ider concentrically of shaft 1, is-an internal-tooth gear-wheel T. and meshing with the same is a gear-pinion 8 secured on the inner-end of a short shaft 9 journaled in the adjacent side of the frame and equipped at its outer end witlra handle 1Q, adapted to be turned in the direction indieated by the arrow, Fig. 1.. for the purpose of imparting movementin the same direcan arm 13 occupying said recess and a notch 14: in the wall formingsuch recess, so that as the cylinder is rotated said arm shall engage the rearend or edge of lug l2 and be caused thereby to swing backward until it is capable of being dragged over the outer or-u per face of said lug, this action of the armiiieing yieldingly resisted by a spring 15 encircling the preferably rectangular shaft 16 of which such arm forms a crank, journaled in the heads or ends of the cylinder,

the said spring being secured at one end to said shaft and at the other bearing against the cylinder as shown in Fig. 1-2. Shaft 16 is provided at a plurality of points, preferably three, with projecting grippers or jaws 17 adapted under the action of said spring, to turn with said shaft 16 the 'instant crank-arm 13 clears-lug 12, and snap down upon the outer side of the contiguous edge of the non-slotted portion of the cylinder and clamp down on and to the same the front edge of a sheetof paper 18. at that time projecting forward-from the table, and to insure the printing of the sheets at corresponding distances from their top or upper marg1ns,a guide 19 is secured ,to the table, consisting of a slotted angle plate fitted on a screw 20 projecting from the table and clamped to the latter at the desiredpoint of adjustment by a nut 21.

The sheets of paper to be printed are fed forward on the table one at a time, and to insure side margins of corresponding width on all of the sheets we rovide a series of stops -22 on a rock-shaft 23 ournaled in the upper ends of the sides of the frame and depending into the slot of the cylinder at times and adapted when so positioned to limit the distance which a sheet can be inserted. Once in each revolution of the cylinder the stops 22 are engaged and pressed aside by the shaft of the grippers, moving upwardly and forwardly until said shaft and the cylinder car rying the same underlies them, this movement of the stops and shaft occurring against the resistance of the spring 2 1 encircling said shaft and secured to the same at one end at 25, and to a pin 26 projecting from the adjacent side of the frame. The said movement of the shaft causes the angular detainers 2 to be swung downwardly and rearwardly until suiiiciently close to the table to prevent a second sheet of paper be-' ing fed into the machine, the said detainers being held in this position during the next half revolution of the cylinder because the non-slotted portion of the latter prevents the stops from swinging downward. \Vhen said half revolution is completed and the sheet engaged by the grippers has been with drawn completely from the table, the slotted portion again registers with the stops and as a result the latter under the action of the spring 25 snap down into the slot of the I which position it is ready to be engaged the grippers in passing.

28 indicates a series of anti-friction rolls supported in the same horizontal plane by the sides of the frame and engaging and supported by a plurality of said rolls at all times, is a reciprocatory frame, consisting of side bars 29,. having upwardly projecting pins 29" and cross bars 30 connecting the ends of the side bars. A frame 31 is adapted to rest upon the reciprocatory frame and is v provided with longitudinal series of holes 31 to receive the pins 29 and be held thereby against creepage upon the reciprocatory frame, a suflicient number of said holes be-, ing provided to permit of longitudinal adjustment of frame 31 of the reciprocatory frame to enable the person in control to effeet a variation of side marginal space on the sheets printed, it being understood that the frame 31 is a skeleton frame with an opening in width substantially equal to the length of the cylinder and of length preferably equal to half the circumference of the cylinder and is designed as a support and carrier for the ink pad 32 and for a sheet 33 of thin silk or equivalent fabric which in turn forms the direct support for a stencil 34 in the form of a sheet of waxed paper or its equivalent 35 indicates an inking roller parallel with and vertically below the shaft 4 of the cylinder and also below the reciprocatory frame mounted on rollers 28, the spindles of said roller being journaled in the front ends of a pair of arms 36 hinged or pivot-ed on a cross rod 37 connecting the sides .of the frame. During the rearward movement of said reciprocatory frame, which movement is that which takes place when the actual printing of the paper occurs, the roller is elevated against the pad, and for the purpose of elevating the roller, wemount a vertical rod 42 slidingly in one of the sides of the machine frame and equip said rod' at its lower end with a collar 43 and with an antifrictionroller 44 occupying the recess in the end of the cylinder, the collar underlying an extension of one of the hinge-arms 36 of the inking roller so that the Weight of the latter is utilized to hold the roller of said rod down near the wall-of said recess, the rod being equipped with a rigid collar 46 playing in a vertical slot 47 in the side of the frame to limit the vertical movement of the rod. A spring 48 on rod 42 is interposed between collar 43 and a rigid collar 49, said spring holding the collar elevated but capable of yielding downward with the inking roller, if necessary. For the purpose of elevating the inking roller and forcing it up against the overlying pad, a substantially semicircular curved track 50 is secured to the cylinder iirtlie recess thereof, and at one end said track extends gradually outward at 51 toward the wall of the recess so as to pass under the roller 44, of said rod .and' gradually elevate the latter and the inking roller, it being noticed in this connection that the roller is lifted just before the forward movement of the stencil-carrying frame ends and that it is completely elevated by the time the rear end of the pad and stencil is disposed vertically over it. The body portion of said track maintains the roller elevated for nearly the full rearward movement of the stencil and then just before said movement is completed the roller travels downward upon the opposite end 52 of said track which likewise slopes gradually outward toward the wall of the recess so that, as it passes under said roller 44, the inking roller descends into con tact with the underlying inking plate.

For the purpose of causing the cylinder to impart reciprocatory movement to the stencil-carrying frame, we provide the fol-- lowing mechanism :53 is a peripherally grooved wheel journaled on one end of the cylinder and provided with a circular recess 54 in its outer face and a notch 55 in the inner edge of the wall forming such recess, and secured to said wheel in a recess 56 is a preferably spring plate 57 which has its free end projecting into the recess 54 and terminating in about the radial line of the adjacent side of the notch wheel 58 journaledon the shaft 4: between the adjacent side wall of the main frame and the wheel above described, fits snugly against thc latter and is provided with a similar recess 59 and notch (30 and also with a recess 31 provided with a spring plate (l2, project ing at its free end into the recess 55), the wheels being disposed in opposite directions so that their recesses 54 and 59 form a common chamber and their spring plates 57 and (32 project in the same direction. (33 is an arm projecting rigidly from the cylinder into the said common chamber and having its outer end bifurcated at (if and pivotally carrying a dog (55 in said bifurca tion, the outer end of the dog being adapted A similar to alternately enter notches 55 and 60 through, the action of the spring plates of the companion wheels for the purpose of alternately locking said wheels to the cylinder. A flexible cable 66, doubled around a guide sheave 67 suitably journaled on an arm (38 projecting from the adjacent side of the main frame, has its upper portion engaging the grooved periphery of wheel 53 and secured thereto at its end as at 69 and its lower portion extending horizontally rearward to the rear end of the reciprocatory frame to which it is attached as shown at 70 or otherwise. A second flexible cable 71 is attached at its front end to the front end of the-reciprocatory frame at 72 and at its rear end engages the grooved periphery of wheel 58 and is attached to the same at 73.

Just prior to the engagement of the grippers with a sheet of paper projecting from the table over the'cylinder in the path of saidgrippers, the rearward movement of the recipro :atory frame terminates and as it terminates the spring plate 57 of the inner wheel engages the inner end of the dog and rocks the latter, this engagement taking place at the moment the notches 55 and (SO in wheels 53 and 58 register, so that the outer end of the dog swings from the notch of the outer wheel into the notch of the inner wheel and thus locks thelast-named wheel rigidly to the cylinder in order that as the latter continues to rotate, said inner wheel shall rotate in the same direction and thus through the medium of the doubled cable, impart forward travel to the reciprocatory frame, such travel of said frame, through its connection with the other cable, pulling the latter forward so to cause the connected wheel 58 to rotate backward at the same speed. At the end of the next half revolution of the cylinder said wheels have each rotated a corresponding distance in opposite directions, this action resulting in the reregistration of their notches 55 and 60, this reregistration occurring just as the spring-plate of the outer wheel engages the inner end of the dog so as to rock the latter and swing its outer end out of the notch of the inner wheel and into the notchof the outer wheel for the purpose of releasing the inner wheel from the cylinder and locking the outer wheel to thesame, so that as the cylinder continues to 1'0- tate the corresponding rotation of the outer wheel winds the cable 71 thereon and conse quently pulls the reciprocatory framerearward, this rearward movement of the frame through the medium of the cable 66 turning the inner wheel backward. At the end of the second half revolution of the cylinder, said notches are again disposed opposite each other to permitthe spring plate of the inner wheel to again force the dog out of the notch of the outer wheel into the notch of the inner wheel, this action taking place just prior to the engagement of the grippers with the next sheet of paper, the previous sheet during the revolution of the cylinder described, having received an impression from the stencil orthe cylinder and stencil or printing surface,

said paper is carried by the grippers up past the friction rolls 74 spaced at suitable intervals on a rod 7 5 journaled in the sides ofthe machine frame. ,As the grippers release the front edge of the paper, the latter through its resiliency, will swing rearward as indicated by the arrow, Fig. 4, over the friction rolls and down upon a table or chute table 76 which inclines downwardly and rearwardly from saidfriction rolls, and is supported as shown or otherwise by the machine frame and preferably has an upturned lip 77 at its rear end to prevent the paper as its rear edge passes above its friction rolls and is thus released from sliding over the table.

78 indicates a rod paralleling and arranged rearward of shaft'23 and secured to the opposite sides of the machine frame'and secured to said rod is a series of curved guards 7 8 which extend downward and forward and occupy a plane slightly'outward of and parallel with the periphery of the cylinder for the purpose of guarding against the paper swinging downward and forward at its rear end after it is completely withdrawn from the feed table, and thus becoming defaced by premature contact with the stencil or printing surface.

When it is desired to print sheets 'of paper by means of type instead of by stencil, the roller 35 is removed, and the stencil-carrying frame is replaced by a type-carrying frame 79, having a series of holes 79, corresponding to holes 31 of frame 31 for engagement with pins 29 of a reciprocatory frame when the stencil-carrying frame is removed,

the frame 79 being equipped with type, as shown at 7 9* for engagement by an inking roller hereinafter described. The shaft 4; is provided near each end with a crank arm 80 having outwardly projecting bosses 80 and journaled in said Losses are rods 81 equipped with downwardly extending arms 82 pressed yieldingly forward at their lower ends by means of helical springs 83 mounted on the bosses and pressing at their outer ends down upon the arms and at their opposite ends upwardly against the crank arms 80. An inking roller 84 has a spindle 85 projecting from its ends and journaled in said spring-pressed arms, a spring-actuated pin.86 carried by one of the arms extending across the notch 87 in such arm, to hold the roller reliably in position and yet permit of its easy and quick removal when desired, the said roller bein removed (or raised out of operative position), when the machine is used in connection with the stencil. The

"pressure of the springs 83 holds the roller pressed against the inner or surface of the cylinder so as to receive a coating of ink byv rotating against such surface, ink being applied to such surface at suitable intervals by the attendant, and in order to have an even distribution of the ink on the cylinder and hence on the type, because the roller rides over the surface of the type when the frame carrying the same moves forward, the ends of the cylinder are cast with inwardly projecting cam tracks 88 which engage the contiguous ends of the spindle alternately and thus causes the roller to slide endwise whilerotating in contact with the said inner surface of the cylinder, the inwardly projecting flanges of the end walls of the cyl- I inder being formed with 'cam portions 89 and 90 which alternately pass under the lower ends of the spring-pressed arms 82. The cam portions 89 pass under. arms 82 just before the slot of the cylinder moves under roller 84 for the purpose of first elevating said roller slightly so as to raise it from the inner wall of the non-slotted portion of the cylinder and thus avoid pushing any ink off said portion through the slot ontot-he type .face, and then permitting arms 82 to be ressed downward so as to project said inking roller slightly outward through the slot of the cylinder to permit it to come into engagement with the type'79 to ink the same. The inking roller remains in engagement with the type as the latter are moving rearwardly unitl the cam portion 90 passes under and again elevates arms 82 a sufficient distance to raise the roller 84 into the cylinder and then said cam permits spring 83 to press said arm 82 downwardly until the roller is again in engagement with the inner or inking surface of the cylinder, this reelevation of the inking roller occurring just before the gripper-carrying shaft reaches said roller so that the paper shall not come into contact with the latter. It will thus be seen that for half the revolution of the cylinder the inking roller is in engagement therewith and that for the other half said roller projects through the slot of the cylinder and applies-ink to the forwardly moving type.

From the above description it will be 'ap parent that we have produced a machine of the character described embodying the features of advantage enumerated as desirable and we wish it to be understood that we reserve the right to make all changes in the form, proportlon, detail construction and organization of the parts-properly falling within the spirit and scope of the invention.
